--individuals or -i leads to TypeError: 'method' object is not iterable, in colab

I work in a colab, trying to generate documentation with instances from an ontology.

Command: !ontospy gendocs -o /content/drive/MyDrive/Temperatur/Ontology/LingTempOntOct2023docs/ontospy_gen_docs -i --type 2 /content/drive/MyDrive/Temperatur/Ontology/LingTempOntOct2023/lingtempontology_oct24_2023_ontoology_rdf.owl -v

Expected result: generation of documentation, including instances.

Actual result:

TypeError: 'method' object is not iterable

Please note that this command in the same colab generates all the documentation. The only difference is the absence of the -i or --individuals tag

Command: !ontospy gendocs -o /content/drive/MyDrive/Temperatur/Ontology/LingTempOntOct2023docs/ontospy_gen_docs --type 2 /content/drive/MyDrive/Temperatur/Ontology/LingTempOntOct2023/lingtempontology_oct24_2023_ontoology_rdf.owl
